Brother of evil = unlucky, or my brother is friend, chief of the tribe of Naphtali at the Exodus (Num. 1:15; 2:29).
Ahira
Ahira son of Enan is named four times in the book of Numbers, always as the leader of the tribe of Naphtali. He is counted at the first census alongside the other heads of tribes, appears in the camp order, and on the twelfth and last day of the offerings, brings his gift for the dedication of the altar: a silver charger, a silver bowl, a golden spoon full of incense, and animals for sacrifice. Every tribe’s leader brings the same, nothing more and nothing less. When the camp sets out from Sinai, Ahira leads his tribe’s host. Numbers 7 gives his offering in full.
